22What kind of food would you bring to the South Pole?
23Because of the cold conditions, food at the South Pole regularly freezes over. It can take from several hours to days for food to thaw completely. The weather can also make it very difficult to prepare food. Because of this, some South Pole explorers use a dried meat product called pemmican to keep their energy level up. Since pemmican does not freeze or require a lot of preparation and it does have a significant amount of calories, it is the perfect food for South Pole explorers.
